Funnily enough, in my family the recipes were passed down from the men. Do I change my grandfather's recipes? Well, it was so obviously already changed from my great-great-grandfather by the time it got to me, so why not? I mean... spaghetti in the tomato sauce, rather than being served on the side, is apparently a New World thing and not a European thing--but that, and adding the Spanish chorizo that definitely is not Italian, and then adding favorite local brands (thankfully, from companies that are still going strong a generation later) to be written down in the recipe book... So, yes, I totally experiment with it and I expect any descendants of mine to do the same.
